Watford locks are beautiful in the sun despite the steady roar of traffic from the M1 nearby.  We tend to come here when it is not likely to be busy out of season, as it is quite a bottleneck, so that means the weather isn't usually so good.  Funny how a utility company always seems to install a wire in the middle of the scene to add character to an image.  Moored for lunch below Crack's Hill and walked to the top for a picnic.  This is about the only high ground for miles around, apparently a glacial outlier, so the views are spectacular.  You can see the relatively new Yelvertoft Marina from the top, as the canal winds around on its way on to Leicester.  We turned there later to moor in Crick for the night.
